July 10, 2026 /SemiMedia/ — Micron Technology said it will accelerate its U.S. fab and technology investment plan, raising its expected cumulative capital spending through 2035 to more than $250 billion.

The new figure marks a significant increase from the company’s previous $200 billion investment plan. Micron said the additional spending is intended to deepen its domestic semiconductor manufacturing capabilities and support its long-term goal of producing 40% of its DRAM chips in the United States.

Micron said its first advanced wafer fabrication facility in Idaho is progressing on schedule and is expected to produce its first wafers in mid-2027. The fab is expected to play a key role in rebuilding Micron’s domestic supply chain and expanding capacity for next-generation high-end memory chips.

As part of the investment plan, Micron will commit up to $3 billion to strengthen the U.S. semiconductor supply chain ecosystem. This includes $500 million in strategic financing for GlobalWafers to support upgrades at its 300 mm virgin silicon wafer facility in Texas.

Micron and GlobalWafers will also sign a 10-year long-term supply agreement to secure stable raw silicon wafer capacity for Micron’s future manufacturing operations. The two companies also plan to explore next-generation wafer technologies and related process innovation.

Industry analysts said Micron’s expanded investment plan is not only a capacity expansion by one company, but also part of a broader U.S. effort to build a more complete domestic semiconductor supply chain covering materials, wafer manufacturing and advanced memory.

For the memory industry, stable 300 mm silicon wafer supply will be important for future DRAM and HBM capacity expansion.

AI infrastructure spending is driving strong demand for high-end DRAM, HBM and enterprise storage. At the same time, capital spending cuts during the previous memory downturn have delayed new capacity additions. Micron’s larger U.S. investment could improve long-term capacity visibility and strengthen supply assurance for key customers.

From an industry perspective, Micron’s plan to expand U.S. DRAM manufacturing, support domestic silicon wafer supply and secure long-term material agreements will strengthen its strategic position in the AI memory cycle.

As global memory demand continues shifting toward higher bandwidth, higher capacity and lower power consumption, competition among memory makers in capital spending and supply chain control is expected to intensify.
